And How We Estimate It Before We Install
A solar system earns in two ways at once: it saves you the expensive power you didn't buy, and it credits you a payment for the surplus sold to the grid. We'll explain exactly how that works - and you can play with the numbers yourself.
The Feed-in Tariff Arrangement in Four Steps
The mechanism is simple: the power you generate supplies your own use first, and anything beyond that is sold to the grid at a fixed, guaranteed feed-in rate. A bidirectional meter separately measures what you drew from the grid and what surplus you fed back - which sets both your savings and your payment.
The System Produces and Feeds the Grid
The rooftop panels produce electricity through the day. A bidirectional meter separately measures how much you produced and how much you consumed - all flowing through the grid's infrastructure.
First: Self-Consumption
The electricity your system makes powers your own use right away, in real time - the most valuable part, because each such kWh saves you the ~64 agorot you'd have paid the grid.
The Surplus - They Pay You For
Whatever you produced beyond what you used is sold to the grid. For that surplus the grid pays you 48 agorot/kWh - a rate locked for 25 years (more in cities with the Urban Premium), plus VAT.
Profit = Savings + Payment
Your benefit is made of two parts: the expensive power you didn't buy (savings), and the payment for the surplus you sold. The more of your own sun you consume, the bigger the profit.
Play With the Numbers
Pick a system size and how much you consume yourself, and watch the annual benefit build up - bill savings plus a payment for the surplus.

Produces about 13,200 kWh per year in Israel
The share you consume out of what the system makes. The rest is sold to the grid.
4,620 kWh × 64 ag you didn't pay
8,580 kWh × 48 ag paid to you
Notice? Every kWh you use yourself is worth 64 agorot - more than the 48 they pay you for surplus sold to the grid. So it pays to use as much of your own sun as possible, and only sell the remainder.
Illustrative estimate only - not a price quote or a guarantee of return. Based on an average yield of ~1,650 kWh per kWp per year and approximate 2026 tariffs (residential rate incl. VAT ~64 ag, feed-in 48 ag locked for 25 years). Actual figures depend on your roof size, orientation, consumption and tax status, and are updated by the Electricity Authority.
Power You Use = 64 ag
Every kWh you consume from your own system is a kWh you didn't buy from the grid at 64 agorot (incl. VAT). That's the direct saving - and it's worth the most.
Power You Sell = 48 ag
For surplus sold to the grid you're paid 48 agorot/kWh - still a nice profit, but less than the saving. In eligible cities the Urban Premium adds about 6 more agorot.
Bottom line: it's better to consume as much of your own sun as possible in real time (or store it for the evening) - and sell only what's genuinely left over.
How We Estimate the Profit in Advance
Our estimate isn't a guess - it's grounded in real data from your roof and your electricity bill.
We Measure the Roof
The available roof area sets how many panels fit, and from that the system size in peak kilowatts (kWp).
We Check Orientation and Shading
A south-facing roof with no shade yields the most. Orientation, tilt and shading from trees or nearby buildings all affect the yearly output.
We Translate to kWh per Year
In Israel each kWp yields roughly 1,600-1,700 kWh per year on average. Multiply by the system size to get an annual production estimate.
We Cross It With Your Bill
From your consumption profile we estimate how much you'll use yourself and how much will be sold, then translate both into shekels - savings and payment.
Tariffs are set by the Electricity Authority and updated periodically, and the residential rate has risen steadily in recent years - which grows the saving over the system's ~25-year life. That's why our estimate is always conservative: we'd rather surprise you for the better.
